Promession

Promession is an idea of how to dispose human remains by way of freeze drying. The concept of promession was developed by Swedish biologist Susanne Wiigh-Mäsak, who derived the name from the Italian word for "promise" (promessa). She founded Promessa Organic AB in 1997 to commercially pursue her idea. The company went bankrupt in 2015 without being able to produce a functioning facility. Critics questioned the technical feasibility of the process.

The idea of promession involves five steps:

Promession as a functional method is questioned. No facility for promession has been built or put into service. Critics argue that there is a physical impossibility to atomize a freeze dried human body in this way.

Promessa Organic AB was liquidated in 2015 without constructing a facility.
